Embodiment 1

[0099] In this embodiment, when the UE initiates offline detachment from the eHRPD network, it carries a special instruction from the network layer to notify the network side to release all PDN connections and its resources. For details, see Figure 4 and the following steps to analyze:

[0100] 1. The UE decides to initiate a detach from the eHRPD network.

[0101] 2. The UE sends a VSNCP Termination Request (VSNCP Terminate-Request) signaling to the HSGW. The request carries a "detach" indication, notifying the HSGW that all PDN connections, resources, and contexts need to be released, instead of releasing a single PDN connection.

[0102] The detachment instruction can be a newly defined identification parameter, or a new value defined by an existing parameter PDN-ID, that is, an escaped PDN-ID. It is necessary for the HSGW to be able to resolve that the UE's intention is to detach rather than delete a certain A PDN connection.

[0103] Wherein, the escaped PDN-ID means ...

Embodiment 2

[0114] In this embodiment, when the UE initiates offline detachment from the eHRPD network, the network layer does not carry a special instruction to notify the network side to release all PDN connections and resources. For details see Figure 5 And the following steps to analyze:

[0115] 1. The UE decides to initiate a detach from the eHRPD network.

[0116] 2. The UE sends a VSNCP Termination Request (VSNCP Terminate-Request) signaling to the HSGW. The request does not carry the PDN-ID, because in the existing operation, each VSNCP termination request signaling carries the PDN-ID, indicating which PDN connection the signaling serves, and now the signaling does not carry any PDN -ID, the HSGW can analyze that this signaling serves all PDN connections, and it is necessary to release all PDN connections, resources, and contexts, instead of releasing a certain PDN connection separately.

[0117] 3. The HSGW receives the VSNCP termination request signaling. According to the f...

Embodiment 3

[0126] This embodiment is an optimization method for notifying the network side from the link layer to release all PDN connections and their resources when the UE initiates offline detachment from the eHRPD network. For details, see Image 6 And the following steps to analyze:

[0127] 1. The UE decides to initiate a detach from the eHRPD network.

[0128] 2. The UE sends an LCP Terminate-Request (LCP Terminate-Request) signaling to the HSGW.

[0129] Because the LCP session serves all the PDN connections, as long as the HSGW receives the LCP termination request, it will release all the PDN connections, resources and context, instead of releasing a certain PDN connection separately.

[0130] 3. The HSGW receives the LCP termination request signaling. According to the request signaling, it resolves to release all PDN connections of the UE, and sends the LCP Termination Ack (LCP Terminate-Ack) signaling to the UE, notifying the UE that it has received the request to detach. s...

Abstract

The invention discloses an optimization method and an optimization system for to-adhering of a terminal from a network side, and an access gateway. The optimization method comprises the following steps that: the terminal transmits a request signaling for requesting to adhere to the access gateway, wherein the request signaling is a terminate-request signaling of a network layer or a terminate-request signaling of a link layer; and the access gateway releases information and resources of all public data network (PDN) connections of the terminal at the network side. By the invention, when the terminal transmits the request signaling once, the operation of releasing a plurality of PDN connections can be realized; therefore, when the terminal is to adhere, the steps can be uniformed, the time and the signaling can be saved and the system burden can be relieved.

Description

technical field [0001] The present invention relates to the field of mobile communication, in particular to an optimization method and system for terminal detachment from the network side and an access gateway. Background technique [0002] The Evolved Packet System (EPS) in the 3rd Generation Partnership Project (referred to as 3GPP) is formed by the Evolved Universal Terrestrial Radio Access Network (Evolved Universal Terrestrial Radio Access Network, referred to as E-UTRAN), Mobility Management Entity (MME for short), Serving Gateway (S-GW for short), Packet Data Network Gateway (P-GW or PDN GW for short), Home Subscriber Server (HSS for short), 3GPP Authentication, Authorization and Accounting (AAA for short) server, Policy and Charging Rules Function (Policy and Charging Rules Function, PCRF for short) entity and other supporting nodes. [0003] figure 1 It is a schematic diagram of the system architecture of the EPS supporting multiple different access technologies....
